dc.description.abstract | Piezoelectric nanogenerators (PENGs) have gained attention as sustainable energy harvesters for wearable electronics and IoT systems by converting ambient mechanical energy into electricity. This study demonstrates a high-performance flexible PENG based on poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) nanocomposite films loaded with graphitic carbon nitride (g-C₃N₄) nanofillers at varying concentrations (0, 1, 3, and 5 wt%). Structural analyses via X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) validated the homogeneous dispersion of g C₃N₄ within the polymer matrix and its role in enhancing the electroactive β-phase content. When subjected to mechanical excitation via electrodynamic shaker testing, the 5 wt% g C₃N₄/PVDF-HFP composite achieved optimal electrical outputs, generating an open-circuit voltage of 21.2 V and a short-circuit current of 14.24 µA—a marked improvement over pristine PVDF-HFP films. The performance enhancement correlates with the filler-induced polarization and crystalline phase modification in the polymer. These findings underscore the viability of g-C₃N₄-reinforced PVDF-HFP nanocomposites as efficient, flexible energy harvesters for self-powered wearable technologies. | en_US |
